In a word, can be according to actual conditions, carry out nimble, diversified division to the distribution of second air supply region in second air-out structure circumference, as long as at second air-out structure pivoted in-process, can satisfy following condition through this division: the combination of the second air supply area and the fixed first air supply area (or the first air supply area in the first air supply unit) which are alternated in the circumferential direction changes the local air supply amount and/or the air supply direction of the air outlet. The second air supply regions may be classified, for example, at least one second air supply unit 522 may be disposed along the circumferential direction of the second outlet structure 52, and the second air supply unit 522 may include a plurality of second air supply regions with different air supply amounts and/or air supply directions. As similar to the layout of the first air supply units, a plurality of second air supply units connected in series or spliced in series may be included in the circumferential range of the second outlet structure 52, the layout of each second air supply unit may be the same or different, each second air supply unit may include one or more second air supply regions with different air supply amounts and/or different air supply directions or partially the same air supply directions, and in the case that the second air supply unit includes a plurality of second air supply regions, the plurality of second air supply regions may be connected in series or spliced in series. In a word, according to the actual situation, the distribution of each second air supply area in the second air supply unit and the second air supply unit in the circumferential direction of the second air outlet structure can be flexibly and diversely divided, as long as in the process of rotating the second air outlet structure, the following conditions can be satisfied through the division: the local air supply amount and/or the air supply direction of the air outlet are changed through the combination of the second air supply unit (or the second air supply area in the second air supply unit) and the fixed first air supply unit (or the first air supply area in the first air supply unit) which are alternated in the circumferential direction.
Through the arrangement, in the rotating process of the second air outlet structure 52, along with the circumferential rotation of each second air supply area along the second air outlet 52, the local air supply direction of the air outlet 5 is changed, the phenomena of overlarge local air quantity, local air supply dead angles and the like caused by the single air supply direction of the fixed air outlet are effectively avoided, the rotation-type directional air supply is realized, the heat exchange of the whole indoor space is facilitated, the air outlet performance of the indoor unit of the air conditioner is improved, and the user experience is obviously improved. Furthermore, the air supply flexibility is further improved by providing a structure in which the local air supply amount and/or the air supply direction are changed inside the water receiving tray 51.
With further reference to fig. 5 and 6A, in a specific embodiment, four first air supply units 511 are arranged at positions lower than the inner side of the water collector 51 along the circumferential direction, each first air supply unit 511 is divided into three first air supply regions, namely an air supply region a 15111, an air supply region B15112 and an air supply region C15113, and the air supply amounts of the three first air supply regions are substantially the same but the air supply directions gradually tend to be horizontal; the second air outlet structure 52 is provided with four second air supply units 522 along the circumferential direction, each second air supply unit 522 is divided into three second air supply regions, namely an air supply region a 25221, an air supply region B25222 and an air supply region C25223, and the air supply amounts of the three second air supply regions are substantially the same but the air supply directions gradually tend to be horizontal. Through the rotation of second air outlet structure 52 relative to water collector 51, each (first, second) air supply area can present multiple combination modes, so that the local shape of air outlet 5 is changed alternately.
It can be understood that the structural form of each air supply region on the (first and second) air outlet structure is only a simple example, in an actual product, the form of the air supply region can be flexibly adjusted according to requirements, for example, the whole circumferential direction is a wavy annular structure to realize alternate air supply, the whole circumferential direction is an increasing or decreasing annular structure to realize periodic air supply, or the circumferential direction is a special-shaped structure which can be flexibly changed at will, and the like, and each air supply region may be continuous or discontinuous, for example, the air supply region is only provided at a part of positions. In addition, the distribution position of the first air supply area on the inner side of the water receiving tray 51 can be flexibly adjusted, for example, the inner side of the water receiving tray 51 is completely improved along the axial direction.
As shown in fig. 7A, 7B, and 7C, fig. 7A shows a state of the air conditioning indoor unit of the present invention when air blowing region C1 is aligned with air blowing region a1, fig. 7B shows a state of the air conditioning indoor unit of the present invention when air blowing region C1 is aligned with air blowing region a2, and fig. 7C shows a state of the air conditioning indoor unit of the present invention when air blowing region C1 is aligned with air blowing region a 2. Taking the example of the (first and second) air supply units as shown in fig. 5 and 6A, in which four (first and second) air supply regions with gradually changing air supply directions are respectively arranged in the circumferential direction on the (first and second) air outlet structures, the principle and process of realizing alternate air supply by the air conditioner indoor unit according to the present invention will be described below with reference to fig. 7A, 7B and 7C.
For any set position, for example, regarding the position near the blowing area C1 in this embodiment, taking the position right below the blowing area C1 as the center of a circle, referring to fig. 7A, when the blowing area C1 is aligned with the blowing area a1, the position farthest from the center of a circle can obtain a milder air volume, and the position closer to the center of a circle is approximately a blowing dead angle, that is, in this case, if the user feels weak to cooling/heating at the position closer to the center of a circle, that is, the cooling/heating effect is weak; referring to fig. 7B, when the blowing zone C1 is aligned with the blowing zone a2, a more concentrated air volume is obtained at a position closer to the center of the circle, where the user feels significant cold/hot impact; referring to fig. 7C, when the blowing zone C1 is aligned with the blowing zone a2, a position farther from the center of the circle can obtain a proper amount of air tilted outward, which is comfortable for human body.
Constantly alternate between each second air supply region through second air-out structure to combine in the position of difference and the first air supply region of first air-out structure, make the body of user in the same position feel more diversified, avoided appearing because only single air supply region appears the user and feels obvious cold/thermal shock or to the weak phenomenon of refrigeration/heating effect when aiming at this position, thereby promoted user experience. It can be understood that the combination of the multiple air supply areas is not limited to be completely aligned, for example, the air outlet may be a gradual combination structure formed by the second air outlet structure and the water receiving tray in the continuous rotation process.
It can be seen that in the preferred embodiment of the present invention, the water receiving tray 51 is used as the first air outlet structure, the second air outlet structure 52 is set to be capable of rotating relative to the water receiving tray 51, and the structure of the butt joint position of the (first and second) air outlet structures is respectively improved to include a plurality of (first and second) air supply units with gradually changed air supply directions, so that the problem of poor user experience caused by single air supply is avoided, the phenomena of long-term existence of an air supply dead angle region, long-term discomfort of local air supply and the like are reduced, the alternating quantitative and/or directional air supply of the air outlet along the circumferential direction is realized, the heat exchange of the whole indoor space is facilitated, the air outlet performance of the indoor unit of the air conditioner is improved, and the user experience is obviously improved.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments.
